Description
Technical Field
The invention belongs to the technical field of food processing, and particularly relates to a potato cake and a processing method thereof.
Background
The traditional cake is processed by taking wheat flour as a raw material, is fine and smooth in texture, soft, easy to digest and rich in fragrance, and is deeply loved by consumers. In the processing process of cakes, a lot of nutrients are lost due to long-time high-temperature baking, part of consumers can generate allergic symptoms to wheat gluten protein, and meanwhile, the content of lysine in the wheat gluten protein is low, so that the nutritional value of the cakes is influenced. With the development of society, the health consciousness of people is also improved, and cakes are required to change the current situation and develop to balanced nutrition, low fat and low sugar.
The potato is an annual herbaceous plant in the solanaceae solanum, is called potato, Chinese yam egg, dutch potato, potato and the like, is one of the oldest crops of human beings, and is the fourth major food crop which is second to rice, wheat and corn in the world. China is the first big potato producing country in the world, and potatoes contain high carbohydrates, protein and VC、VBl、VB2Carotene, phosphorus, iron, calcium and other nutrient components. The potato protein is complete protein, contains 8 amino acids essential for human body, and has high utilization rate up to 71%, and high lysine and tryptophan content.
Although potatoes have high nutritional value, the potato whole flour does not contain gluten protein and has no capability of forming a gluten network structure, so the potato whole flour is not suitable for directly processing cakes, and the gluten network structure in the cake batter can be weakened along with the increase of the addition amount of the potato whole flour, so that the cake surface is sunken, the volume is reduced, and the flavor is poor.
Disclosure of Invention
Aiming at the defects of wheat flour cakes in the aspects of nutritional value and health care effect in the prior art, the invention aims to provide a potato cake which is comprehensive in nutrition, does not contain wheat gluten protein and has good taste and a processing method thereof.
In order to achieve the purpose, the invention provides the following technical scheme:
the invention provides a potato cake which is prepared from the following raw materials in parts by weight:
100 parts of potato whole powder; 2-10 parts of guar gum; 5-30 parts of pregelatinized starch; 5-15 parts of dietary fiber; 1-3 parts of salt; 30-60 parts of vegetable oil; 40-60 parts of white sugar; 150-180 parts of eggs; 1-3 parts of baking powder; 1-3 parts of potassium hydrogen tartrate; 10-40 parts of water.
Preferably, the potato cake is prepared from the following raw materials:
100 parts of potato whole powder; 4-8 parts of guar gum; 10-30 parts of pregelatinized starch; 5-10 parts of dietary fiber; 1-2 parts of salt; 30-50 parts of vegetable oil; 50-60 parts of white sugar; 160-180 parts of eggs; 1-2 parts of baking powder; 1-2 parts of potassium hydrogen tartrate; 10-30 parts of water.
Further, the potato cake is prepared from the following raw materials:
100 parts of potato whole powder; 5 parts of guar gum; 30 parts of pregelatinized starch; 8 parts of dietary fiber; 1 part of table salt; 30 parts of vegetable oil; 60 parts of white sugar; 180 parts of eggs; 1 part of baking powder; 1 part of potassium hydrogen tartrate; and 20 parts of water.
according to the potato cake, the guar gum and the pregelatinized starch (α -starch) are compounded, so that the viscosity and the air permeability of the batter can be increased, the quality of the cake is improved, and the cake is fluffy in surface, large in volume and good in taste.
Preferably, the preparation process of the potato whole flour comprises the following steps:
s1, selecting disease-free potatoes, cleaning, peeling, removing bud eyes, cutting into blocks, steaming for 20-60 min, cooling, mashing into paste, and freeze-drying;
s2, crushing the freeze-dried product, and then sieving the crushed product with a 100-200-mesh sieve to obtain the potato whole powder.
The whole potato flour is more dispersed after being sieved, and the baked cake tastes more delicate and tasty.
preferably, the pregelatinized starch is any one of α -potato starch, α -corn starch and α -tapioca starch.
In a preferred scheme, the dietary fiber is any one of cellulose, sweet potato fiber and rape fiber.
The invention also provides a processing method of the potato cake, which comprises the following steps:
(1) weighing the raw materials according to a set proportion;
(2) separating egg white and egg yolk, adding white sugar, salt and vegetable oil into egg white, stirring at low speed with an egg beater, stirring at high speed until the egg white becomes white, foaming, adding baking powder, potassium hydrogen tartrate and water to expand the volume of egg white liquid, and pouring out;
(3) putting the egg yolk into an egg beater to be beaten up, continuously adding the potato whole powder, the guar gum, the pre-gelatinized starch and the food fiber, uniformly mixing, then adding the egg white prepared in the step (2), and stirring at a high speed until uniform paste is formed;
(4) transferring the paste prepared in the step (3) into a baking mold, putting the baking mold into a preheated baking oven, and baking until the surface of the cake is golden;
(5) brushing a layer of boiled oil on the surface of the cake just taken out of the furnace in the step (4), cooling and demoulding to obtain a finished product.
In one embodiment, in the step (2), the low-speed stirring time is 2-10 min, and the high-speed stirring time is 2-5 min.
In a specific embodiment, in the step (4), the paste is transferred to a baking mold and is packaged at the height of 1/2-2/3; if overfilled, the cake may spill out as it continues to puff during baking.
In one embodiment, in step (4), the inner wall of the baking mould is not coated with oil, and the paste is required to adhere to the side wall of the mould when the paste expands during baking of the cake, and the paste expands upwards by virtue of adhesion.
In a specific embodiment, in the step (4), the temperature in the initial stage of the oven is 180 ℃, after baking for 10-15 min, the temperature is raised to 200 ℃, and the baking is continued for 5-10 min.
Compared with the prior art, the invention has the technical advantages that:
1) according to the potato cake provided by the invention, the viscosity and the air permeability of the batter can be increased by compounding the guar gum and the pregelatinized starch, so that the quality of the cake is improved, and the cake is fluffy in surface, large in volume and good in taste; dietary fiber is added to enhance health promotion effect.
2) The potato cake provided by the invention is rich in various nutritional ingredients such as protein, vitamins, phosphorus, iron, calcium and the like, has the lysine content remarkably higher than that of a wheat flour cake, does not contain mucedin, and is suitable for people with wheat allergy.
3) The processing method provided by the invention is simple to operate and easy for industrial production.
